ASKED QUESTIONS
Q. What do I do if the picture starts to break up?
A. Turn both the receiver and the transmitter off and on again. This will reset and allow the
RFX-NLL to select a different channel to use.
Q. What if the LED indicators flash yellow?
A. Make sure that the TX and RX are on matching frequency bands (both 5.2 GHz and 5.8
GHz). Check that you are supplying 8 – 18 volts DC to the RFX-NLL. Reduce the distance
and turn the RFX-NLL off and on again. It can take up to 60sec for the TX and RX to lock.
Q. What if the LED indicators are yellow but I am not receiving any video or audio?
A. If the LED indicators are YELLOW with a quick GREEN blink, then the RFX-NLL is
transmitting information and is working correctly. The GREEN slow flashing indicates there is
no video at the TX side or there are weak signal conditions. Check cable connections
between the transmitter and the camera, the monitor and the receiver, or try a closer distance
between the units.
Q. What if I am using the RFX-NLL within recommended distance guidelines and it is
not working properly?
A. Always maintain a line of sight between the transmitter and receiver wherever possible, as
microwave transmission doesn’t work well through walls or structures. Mount the receiver as
high as possible internally or externally with a clear line of sight to the camera for best results.
Solid walls like brick, concrete, steel and insulated walls dramatically reduce the range of the
RFX-NLL.
Q. Does the RFX-NLL interfere with WiFi 802.11 A, B or G?
A. No, because the layers are fundamentally different and the two systems do not
communicate or interfere with one another.
The RFX-NLL automatically scans the frequency spectrum and avoids any other channels
occupied by other networks. When using more than one system within a small area ensure
the distance between the receivers exceeds 15 feet (5 meters), as the receivers could
interfere with one another.
